1540 is an easy flowing crystal polystyrene designed for extrusion or injection applications. In extrusion, it improves extruder output and thermoforming cycle times when mixed with a high impact polystyrene such as LACQRENE® 7240. Having high gloss, it is particularly suitable for glossy-layer co-extrusion. In injection molding, 1541 possesses low viscosity at high shear rate. It does combine excellent fluidity with a higher softening point that 1810/1811.ApplicationDairy sheet, Cups, Coextrusion crystal, Boxes, Petra dishes, Medical products, Office equipment - e.g. filling trays, CD boxes, Pen bodies, Internal fridge parts.Information provided provided by Total Petrochemicals.Total Petrochemicals acquired former Fina and Atofina plastics product lines.
